Modus operandi and suspects

• The first explosion (Paharganj explosion) occurred outside New Delhi Railway Station. The explosive device was planted in a two-wheeler (generic term used in India for any motorised vehicle with two wheels, such as a motorcycle or a motorscooter). When the bomb exploded, it ripped apart the M S Medicos, a medical shop outside which the two-wheeler was parked. According to Rediff.com the shop was badly damaged with glass strewn all over the street and blood splattered all over the ground. When the explosion took place large number of people were eating golgappas in the adjoining snacks-cum-sweet shop resulting in the high number of deaths in the area.
• The Govindpuri explosion, which took place inside a bus, injured nine people, four critically. 35–40 people were travelling in the bus when the conductor of the bus spotted a suspicious plastic bag which none of the passengers claimed. The passengers were already suspicious as a man had climbed aboard the bus and refused to buy a ticket, according to the BBC, leaving his large, black bag aboard. The driver and conductor of the bus quickly alerted and disembarked the passengers and, by doing so, minimised the damage when the bomb was thrown out of a window. At the time of the explosion, only five people remained inside the bus. However, the driver and conductor sustained injuries in their rescue effort, and the driver's condition was critical according to NDTV. According to the Indian police, the Govindpuri bomb operated on an electronic timer.
• The third and most devastating explosion took place in a very crowded corner of the busy Sarojini Nagar market. According to The Hindu website, the eyewitnesses claim that the bomb was placed in a white colour Maruti van whose front and rear mirrors were shattered due to the explosion. The bomb went off near a vendor using a gas cylinder, which exploded, triggering multiple explosions and leading to an outbreak of fire in a row of shops. Apart from resulting in the death of 43 people and injuring about another 28 people, half-a-dozen clothing shops and a few vehicles parked behind these shops were destroyed due to this explosion.
• It is believed that the explosive used to carry out the blasts is RDX.
• It is also believed that the blasts were connected to Quds Day, on Friday, October 28, 2005, which creates terror world wide, against Israel and United States. To mark the Jumu'atul-Wida, which is the last Friday of Ramadan, as Al-Quds Day, was initiated by Iranian spiritual leader Ayatollah Khomeini, in 1979 to support Palestine Muslims.^[5]

Bomb hoaxes

At least two phone calls reporting fake bombs have been received by the Delhi police, including a false report of a bomb in a school (or a fair) for people with visual disabilities. In addition, there was a phone call reporting a (purportedly fake) bomb near a bank in Khari Baoli before the attacks occurred; the object referred to by the call was a suitcase, in which there were documents, batteries, and wires. In the midst of the attacks, there was another hoax call reporting a bomb going off in the Gole Market.^[13][14]

The Delhi police, after the explosions, sent out messages to the public asking them to report unidentified objects. This led to a wave of reports of "bombs", all of which proved to be either nonexistent or more benign objects, including a "bomb" at the Som Bazaar in eastern Delhi and another "bomb" near the Sanjay Gandhi Hospital.
